Arrays and Java

Just a short post with pretty much all you need to know about arrays in Java:

• http://javabeginnerstutorial.com/core-java-tutorial/java-array-tutorial/ to start with
• http://www.homeandlearn.co.uk/java/java_arrays.html excellent site, from start to end; includes 2D arrays and much more


• http://introcs.cs.princeton.edu/java/14array/ great resource with many examples, but more complex
• Also, it is highly recommended to study Big Java Late Objects (Horstmann, 2013) - chapter 6: Arrays and Array Lists

Below are some additional links about arrays and 2D arrays:

Encryption

A couple of great links on Symmetric and Asymmetric Encryption:

• http://itchyfish.com/advantages-and-disadvantages-of-symmetric-and-asymmetric-key-encryption-methods/

These are also posted under out Network and Security post, but since they are also related to encryption, here they are:

Network and security

A very comprehensive glossary of network terms, obviously not all required for our examinations and syllabus, but they are extremely valuable.
Also, links to how stuff work's networking and security.

• Here is a great Networking Tutorial for beginners with pretty much all computer networking essentials covered.

Although you don't need to memorise the OSI reference model, awareness of the layered nature of networks is very important.

Netbeans and ArrayList

You may want to download and install Netbeans (the use of this IDE is OPTIONAL, but recommended for our IA as it makes life easier. If you are comfortable with Geany, stick to it. You may want to give Netbeans a try, though.

• https://netbeans.org/downloads/8.1 --> We need only the Java SE bundle, then install the EasyUML plugin
• http://www.cs.columbia.edu/~cmurphy/summer2008/1007/netbeans/1_intro.html 

Our last data structure (for SL) is the Java built-in ArrayList:

How to install MySQL Workbench in Ubuntu

Installing MySQL Workbench in Ubuntu is very straightforward, but not always easy to come across.

Hope this quick tutorial helps get the job done without wasting time.

Let us take the most direct approach, using the Terminal to install what we need in order to use MySQL Workbench.

sudo apt-get update sudo apt-get install mysql-server mysql-workbench -y

The above will ask you to type your (user) password. If you have not used the terminal much, be aware that nothing will appear on screen as you type your password. This is a security measure and it is normal.
When the download and installation of the two packages finish, you will be presented with the following screen:

Enter a password that you will easily remember. You may use your Ubuntu user password if you want, but bear in mind that this will be the root password for the MySQL server; this is a individual service and its password is independent from the rest of your Ubuntu system. So you could use any password you want, just make sure you do not forget it!

Now you can open the Workbench, using the search function of your desktop or by typing mysql-workbench in the Terminal.
Next we need to connect to the MySQL service so we can start using the Workbench. You should see a Local instance under MySQL Connections in the main Workbench initial window.

When you click on the Local instance icon/rectangle, it will ask you for the root password of the MySQL service that you set during the installation.
If you do not want to enter the password every time, just save it to the key chain.

If you want to set up MySQL in other platforms, check the following links:

• MySQL Downloads
• Installing and updating MySQL

And that's all, folks! Happy SQL'ing
